Advance Information

LCD Segment / Common Driver with Controller

for Character Display System

CMOS

GENERAL DESCRIPTION

SSD1801 is a single-chip CMOS LCD driver with controller for liquid crystal dot-matrix character display

system. It consists of 105 high voltage driving output pins for driving 80 Segments, 24 Commons and 1 icon

driving-Common. It can display 2 or 3 lines of 16 characters with 5x8 dots format. The double height character

mode and line vertical scroll functions are supported.

SSD1801 displays character directly from its internal 10,240 bits (256 characters x 5 x 8 dots) Character

Generator ROM (CGROM). All the character codes are stored in the 512 bits (16 character x 4 lines) Data

Display RAM (DDRAM). User defined character can be loaded via 320 bits (8 characters x 5 x 8 dots) Character

Generator RAM (CGRAM). In addition, there is a 80 bits Icon RAM for Icon display. Data/ Commands are sent

from general MCU through a software selectable 6800-/8080-series compatible 4/ 8-bit Parallel Interface or Serial

Peripheral Interface.

SSD1801 embeds a DC-DC Converter, Voltage Regulator, Voltage divider and RC oscillator which reduce

the number of external components. With the special design on minimizing power consumption and die size,

SSD1801 is suitable for portable battery-driven applications requiring a long operation period and a compact

size.
